“It is a new challenge for internet companies to have to deal with nation-states attempting to subvert elections,” Zuckerberg said. “But if that’s what we must do, then we are committed to rising to the occasion.”

Zuckerberg says the company plans to work with congressional committees investigating Russian interference in the US election; make political advertising more transparent; increase communication and collaboration with elections commissions around the world and target fake accounts that could be attempting to influence elections.

“I think it is a positive sign Facebook is sending with this,” said Lisa-Maria Neudert, who researches computational propaganda for the Oxford Internet Institute. “I think Mark Zuckerberg is only beginning to realize that this platform that he has built ... to bring people together around the world, can very much be used for political propaganda, for intervention into the elections.”

Neudert has researched computational propaganda efforts during elections in the US and France, as well as Germany, which holds its federal elections on Sept. 24.

She says Facebook’s plan “is a first step” to combat the election interference seen in past elections. But she says Facebook “still has a long way to go.”
